IMPROVEMENT IN MACHINES FOR BURNISHING EDGES 0F BOOTS AND SHOES.

Specification forming part of Letters Patent No. 127,904, dated June 11, 1872.

Specification descriptive of certain Improvements in Machinery for Setting or Burnishin g the Edges of Boot and Shoe Soles, invented by JAMES W. MALOY, of Boston, Suffolk county, Massachusetts.

These improvements have reference to machinery for setting the edges of boot and shoe soles, in which the setting agent is a circular disk, revolving about and in contact with such edge. In such machinery two or more different disks or setting-tools are em ployed, one for the greater part of the sole, which is square, or nearly so, and the other for the shank portion of such sole, which is chamfered off or slopes away at an acute angle, or, in some cases, is round or convex, and necessitates the use of a disk with a sloping or a concave periphery. The purpose of these improvements is to combine the two or more more disks or setting-tools upon one shaft in such manner as to be manipulated and brought into action instantly by the same handle with which the workman supports and guides the tool, the only motion required being simply to twist the handle when the second or last tool is to be brought into play. To this end my invention, as herein explained, consists in the employment of two setting-tools, one disposed about and sliding longitudinally to and fro of the other, the inner one being fixed to the common supporting-shaft, and the other sliding upon but revolving with it and being controlled by a. handle common to the two, in

' such manner that after the inner one has gone through its functions and acted upon the soles edge, to which it is presented by the direct bodily aid of the handle, the outer one, bya twisting motion of the said handle, is advanced and incloses the first,and is presented in proper order to effect its portion of the work.

The drawing accompanying this specification represents in Figure l a plan, in Fig. 2 an end elevation, in Fig. 3 a vertical and transverse section, and in Fig. 4 a vertical and longitudinal section, of a portion of an edge-setting machine embodying my improvements. Fig. 5 is a side elevation of the inner settingtool and its chuck, to behereinafter explained.

In the said drawing, A denotes a portion of the frame of an edge-setting machine, the same being provided with boxes B B, in which rotates a horizontal shaft, 0. The shaft 0 is tubular, and within its boxes a is disposed a tubular rod, D, having its outer extremity or tapering head I) split to form a chuck, substantially after the manner of ordinary drillchucks now in use, the said tapering'head operating with a similarly-formed seat 0 made in the bore of the shaft. In order to advance or retract the rod D within the shaft 0, and by so doing expand or contract its chuck, I form upon its inner extremity a male screw, cl, upon which is screwed one end of a rod, 6, which is inserted within the opposite end of the bore of the shaft, and is provided with a shoulder or enlargement, f, to abut against the'adjacent end of the shaft, and with a hand-wheel, g, to rotate it. The inner and lesser edge-setting disk or tool is shown in the drawing at E as a circular disk, properlyformedto execute the work required of it, a tenon or journal, F, extending from it into the chuck b, by which means it is held firmly in place within the shaft 0. The outer edge-setting tool is represented at G in the drawing as applied to a tubular disk or sleeve, H, which slides upon the outer end of the shaft 0, and is connected with it by an ordinary spline-and-groove connection, the bore of the last-named tool and sleeve combined being of sufficient diameter to easily receive the inner tool E, over which such outer tool slides, as occasion requires.

To effect the sliding of the outer tool to and fro of the inner one, I pivot to the outer cor ner of the frame A, as represented, a forked shipper, I, which embraces the said outer tool and extends into an annular channel, '5, formed therein for its reception. The pivot of the shipper I is the shank or tenon j of an upright handle, J, which is passed through it and the adjacent parts of the frame A, this handle constituting the means whereby the proper motions of such frame are guided and controlled by the hand of the workman. By imparting a twisting motion to the handle the operator is enabled to advance the outer tool and bring it into action upon the sole-edge, or to retract the same and allow the inner one to be brought into use. By this simple arrangement of the two disks and the shipper and handle or their equivalents, I am enabled, without loss of time and without labor, and with little care, to substitute one settingtool for the other, and the invention will be found valuable in the class of machinery to which it is applicable.

0 Zaims.

motion of such handle the outer tool is advanced. or retracted with respect to the inner one, essentially as and for the purposes stated.

3. I claim, in combination with the settingtools before named, the chuck 11, substantially as and for purposes stated.

4. I claim, in combination, the two tools E G, shipper I, and handle J, in connection with the frame A, shaft 0, and chuck b, or its equivalent, the whole operating in manner and for purposes stated.
